THOMAS J. BARLOW, OF BALD KNOB, TEXAS.

GRAIN-FEEDER AND BAND-CUTTER FOR THRASHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 256,620, dated April 18, 1882.

Application filed July 22, 1881. (Model) To all whom it may concern Be it known that I, THOMAS J. BARLOW, of Bald Knob, in the county of Hood and State of Texas, have invented certain new and useful Improvementsin Grain-Feeders for Thrashers and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, and in which- Figurel isaplan view of m yimproved grainfeeder for thrashing-machines. Fig. 2 is a side view, showing the check-board connected to the bell-crank checking orstoppinglever. Figs. 3, 4, 5, 6, 7 are respectively details of the gageboard adjusted to operate against the bellcrank lever, supporting-board, the main driving-wheel, showing the mechanism for starting and stopping the feed apron or belt, the gavel or sheaf binding cord, wire or straw cutter, mechanism for operating the apron-teeth, and an underneath view of the two sets 'of teeth. of the apron. Figs. 8 and 9 are respectively a longitudinal section on line 00 a: of Fig. 1 and a transverse section of my machine or feeder, the cross-section being taken on theline 3 y of Fig. 1. Figs. 10, 11, 12, 13, and 14 are detail views thereof.

This invention appertains to improvements in grainfeeders for thrashing-machines; and it consists of mechanism for cutting the bands of the sheaves or gavels, as they are fed upon the traveling apron or belt; for controlling the feeding of the grain upon or by the apron to the thrasher; for aiding the feeding operation of the apron for the projection and retraction of the apron-teeth; for vertically adjusting the apron-supporting frame, and for arresting the motion of the feedingtable by the action of the main or driving wheel of the feeder, substantially as hereinafter more fully set forth.

For carrying out the foregoing I have 'adopted the device shown in the accompanying drawings.

Referring to said drawings, AA mark sidesupportingpieces,preferablyadapted to receive disks or pulleys a a, one pair larger than the other pair, and arranged the larger ones at the as seen in the same figures. compasses and moves upon the reduced or discharge end of the machine, the smaller ones being disposed at the opposite end. These pulleys are secured one at each end of two shafts, presently referred to. The shaft a of thelarger pulleysis hungtransverselyhetween upper and lowerpieces, a fastened tothe inner faces of the side pieces, A. The shaft a of the smaller pulleys is hung in staples or boxes a, fastened to a cross-piece, a", connecting the outer ends of parallel sliding or adjustable bars a to pen mit the adjustment of the said shaft and its pulleys for tightening the apron encompassing the pulleys. bars a and are provided with elongated slots a which receive adj usting-screws a", to permit of their movement for the purpose above stated. The screws a work in the bars a B is the endlesstravelingapron or belt, composed'of transverse slats b and b connected each about centrally, as seen in Figs. 12 and 13, at each end to flexible belts or straps a", which permits each slat to change its relation to its fellow as it'passes around the pulleys a,

This apron enlesser peripheries of the pulleys a, and is The bars a rest upon the guided in grooves b b in the sides A. In the apron B are arranged, at suitable distance apart, perforated slats b grooved out upon their inner surfaces.

G G are series of teeth, one series projecting through each of the slats b for the purpose of forcing along with the movement of and upon the apron the grain to facilitate or aid the feeding ofthe grain into the thrasher. The

heads b of the teeth 0 are hinged to short axes projecting from the ends of a projection of one of the slats b To the said projection is affixed a stop, I)", (see Figs. 7 and 8,) to limit the retraction of the teeth 0. Arms b are attached to the head b and are adapted to engage with retracting waysD (see Figs. 9 and 10) asthe grain is about to he passed into the thrasher, and thus withdraw the teeth from the grain at that juncture. The teeth 0, each of which consists of. a straight portion or shank and a curved or segmental portion, as shown, are arranged together in pairs and may take the place of the teeth 0. The inner ends of the teeth 0 are connected, each pair, to-a common pin or fixed axis, 0, arranged across.

the groove of the slat b The inner ends of the teeth 0 are provided each with a loop or eye, 0, into which projects a. pin, 0 secured to the head 0 of the teeth. This head is pivoted or hinged in a similar manner as the head 11 of the teeth G to its slat, and is limited in its movement by a stop, a", and likewise provided with arms 0 (see Fig.7,) to permitits manipulation by the ways D in like manner as the head of teeth 0, and by which action it will be noticed that the segmental portions of each pair of teeth 0 will be caused to approach or meet one another when extended through the slat, and thus grasp and carry the grain to be fed into the thrasher. By gravity the head of the teeth will fall downward when the grain has reached the point at which it is delivered into the thrasher, and thus permit the separation and withdrawal from the grain of the teeth.

1) D are the ways secured indirectly to the shaft-supporting pieces a and having their longitudinal portions inclined from the outer or smaller pulley end of the machine downwardly underneath the pieces ai and thence curved upwardly and extended to a point a little above the forward end of the apron supporting and adjusting frame E, presently described, the purpose of which will appear hereinaftcr.

E is the apron supporting and adjusting frame connected to a board, 6?, secured to the sides A, between the pieces o by means of crank-shafts (1, adapted to allow the frame to be raised or lowered to accordingly affect the apron, as occasion may require. To conveniently operate the board (I a lover, a, is pivoted thereto to extend diagonally from the right-hand corner of the forward end of the board (I, and is connected by a link, 0, to the frame E, and by a link, to a sliding block, 0 operated by a screw-bolt, c, with its head accessible from the outside of the machine. The slide 6 under the action of the screw 0, draws upon the lever 0 through the rod 0 when the screw is turned in one direction, or forces it back when the screw is-turned in the opposite direction, according as it is desired to raise or lower the frame E.

It will be observed that the teeth-head arms b and 0 passing along upon the side pieces of the frame IE, will, upon reaching the forward end of said frame, immediately drop down undcr the curved ends of the ways 1), and thus withdraw the teeth at the proper instantfrom the grain being delivered into the thrasher. F is the feeding-table affixed to one side of the feeder, and having endless sectional apron or a number of such aprons encompassing grooved rolls, one of which has a fixed and a loose pullcy,ff. Teeth f affixed to the end of the frame of the table F, secured to the feeding side of the machine, and projecting in grooves in the forward or inner roll of the table, permit the grain upon the table to be carried into the machine without being wasted in falling between the table and the latter.

Affixed to one side of the table is a springyf for the cutter to rest adjust-ably on.

G is the cutter for severing the binding twine, straw, or wire of the sheaves or bundles of grain placed upon the table preparatory to feeding it into-the feeder. It consists of a head, hung or pivoted to a frame, 9, fast cued detachahly (for reversing it to the other side) to the feeder. It being hung in position the cutter is capable of manipulation with relation to the bundle, so as to conveniently cut its hand. A shaft, passes through or into the head and has a crank, which connects with a bar, G, having a series or row of teeth, g Two othcrcranks, G2 it, Fig. 14, connected to the ends of the toothed bar, balance it upon the crank of shaft 9 Those teeth are adapted to take hold of the band of the bundle or sheaf of grain and carry it against the blade g of the cutter, and thus sever it and permit the grain to be spread out. The tooth-operating shaft has a beveled pinion, g which engages a similar pinion, g, upoua shaft, 9 hung in the frame 9'. Upon the same shaft is apulley, 9", around which passes a belt, driving the aforesaid gearing and shafts, in turn reciprocating horizontally the teeth g, which bring the band of the sheaf or bundle against the cutter g severing it.

Gisa guard adj ustablycounectcd,as clearly shown in Fig. 11, to the head g, and arranged above the teeth The belt 9 also passes around or receives motion from a pulley, g upon a shaft, which is driven by a pulley, g, on same shaft, and abclt, g", passed around it and the pulley it upon the main drivingpulley shaft h. The belt 9' passes over the idler-pulley H is a frame fastened upon the cdgewisedisposed boards t' i, the board 41 being secured at the forward end of the machine and the board 11 a short distance therefrom toward thev rear of the machine.

I is a rake having its head ecccntrically couuectcd near its ends to two pullcys,j j, the shafts thereof having their bearings upon a cross-bar,j, of the frame H. In addition to driving the cutter-gearing the belt 9 drives the pulleysj j, which operate the rake, the belt being crossed and passed from the pulley 9 around the said pulleys j. To the head of the rake are attached pendants or armsj having the fingers or teeth j The rake, by the rising and falling and back and forth motion it receives from the pulleys or eccentricsj, pulls or rakes the grain from the table side of the feeder upon the apron well toward the middle and equally upon the pposite sidcofthe apron. It will be noticed that the cutter is supported or connected by a cord, G to a spring, 9 to aid in holding it properly to the grain-bundle while cutting its binding twine, wire, or straw.

J is the check-board, detachably pivoted to the side of the machine opposite that to which the table is attached, and is capable of being reversed side for side of the machine with the table, according to the side of the machine to which it is desired to attach the feeding-table.

the grain from the table upon the apron when said feeding operation becomes greater than the capacity of the apron to feed the grain into the thrasher, whichtchecking operation of the board will more fully appear presently. One arm, k, of this board is connected by a rod, to a bell-crank lever, K, pivoted upon the board i. The same end of the'lever is conneeted by a rod, 70 to a spring, k adjustably connected by a perforated sliding or adjustablebar, 70 and pin 70' to the board 1', to put itnnder tension. The tension or pressure of the lever upon the check-board may be regulated by the adjustable bar and pin. From the op- .posite end of the lever Kdepends ahooked rod,

is, which may have frictional rolls thereon.

k is a belt driven by the double pulley K K (it being designed to pass a belt from the lower pulley, K to the driving-shaft h,) from thence passed around the driving-pulleyf of.

the feeding-table. On its way to the latter pulley it passes against the outside of the frictional roll on the lever-bar 70.

v From the foregoing it will be seen that as the grain, should it begin to pack against the check-board .l by the too rapid feeding of the table, presses against the said board it will be forced outwardly and pull upon the lever K, theopposite end of which will be moved forward. This movement of the lever will carry the rod 7c in the same direction, causing it to draw upon the table-operating belt 70 which will slip the latter off the fast or driving pulley of the table upon the loose pulley, and thus arrest the feeding action of the table until the pressure is taken off the check-board by the feeding out of the grain by the apron. When this takes place, the lever K returning to its normal position and the drawing action of the rod 7c being removed from the belt 70", the said belt will slip back upon the drivingpulley and thus again put the feeding-table into operation. The too rapid action of the feed-table is thus prevented from stopping the feeding-apron and the machine itself enabled to regulate the feeding of the grain upon the apron and from the apron into the thrasher.

L is a gage-board adjustably connected by a screw, l, to the board i, and is capable of being vertically adjusted to vary the size of the passage between the said board L and the apron, and thus regulate the quantity of grain fed by the apron into the thrasher.

M is the main driving pulley or wheel,which receives its motion by belt, preferably from the thrasher, which motion it transmits to the apron and to the rake, the cutter, and the feedtable. Upon the shaft h of the pulleyM is a loose pulley, m, around which passes a belt, m, connecting with apulley upon one of the apron pulleys to communicate motion thereto. The pulley M is provided upon its inner face with two weights, at, which slide in slots a therein, and connected by arms a to a grain into the thrasher.

disk, a The arms a are pivoted in. slots in the disk n to permit their entrance therein when not extended.

N is a lever pivoted at one end to the same side or face of the pulley M, the said end of the lever having a pin or projection, 0, which engages at certain times the pin or projection 0 upon a disk, 0 of the pulley m. Thislever is connected to the disk n by a wire, 0 and a short lever, 0 pivoted in a slot (indicated in dotted lines, Fig. 4) in the lever N. The wire 0 is jointed in the slot of the lever Nand connected to the outer end of thelevero. Through the other end of lever 0 is looped or passed a bent wire bar, one arm, 0 acting as a slide or catch engaging with an eye or staple, P, and the other arm, 0 passing through a hole in and adapted to project at certain times be yond the outer end of the lever N, and engage a pin or projection, q, upon the side of the top frame, H. A spring, 4", is capable ofovercoming the centrifugal action of the weights at by reversing the action or movement of the disk n as the motion of the driving-pulley M is retarded.

The foregoing mechanism, which may be re placed by other and as effective mechanism, and which I reserve the privilege to do, has for its object to stop the motion of the traveling belt-or apron B, which will appear more fully from the following: The wheel or pulley M being set in motion for the operation of the machine, it will be noticed that the centrifugal action will throw the weights n outwardly, which will draw upon the spring 1 and par tially rotate the disk if, having the effect to actuate the short lever 0 which will cause the lever N to be so acted upon as to enable its pawl or projection 0 to engage the projection 0 upon the disk 0 of the apron driving puLey m, and thus transmit the motion of the driving-pulley M to the pulley m and put the apron in motion to effect the feeding of the Simultaneously, or at the same instant, the catch 0 will be with-- drawn from its retaining eye or staple P and the arm 0- be disengaged from the projection on the frame H.

The slackening up ofthe speed ofthepulley M when necessary to stop the feeding of the grain into the thrasher will of course have the effect to allow the weights n to be drawn inwardly by the action of the spring 1", it reversing the position of the disk at", which will return the lever N to-its former position, thus changing the position of the lever 0 and consequently projecting the catch 0 into its eye P and the arm 0 beyond the periphery of the pulley M, and causing it to engage with the projection g on frame H, arresting the motion of the pulley M and securing the leverN in a locked position.

An inclined grain-board, 0, (see Fig. 8,) is affixed to the lower forward end of the feeder to conduct any falling grain into the thrasher.
